To all whom it may concern:

Be it known that I, JAMES SIMPSON, of McKeesport, Allegheny county, Pennsyl- Vania, have invented a new and useful Transfer Mechanism for Hotbed's, of which the following is a full, clear, and exact description,

reference being hadto the accompanying drawings, forming part of' this specification, in 'which I I j Figure 1 is a plan of a hotbed having transfer 'mechanismconstructed and arranged in accordance with my. invention. Fig. 2 is a sectional side elevation of the same on a larger scale taken on the line II-II of Fig. 1. Fig. 3 is a sectional side as located on opposite sides of the longitudinal center line of the hot bed in the positionassumed in transferring a. rolled blank from the center of the bed sidewise to the righthand of the bed andpiling the blank on top of previously transferred blanks; Fig. 4 is a sectional side elevation similar to Fig. 3 showing the transfer mechanism after being operated to transfer and pile a blank on top of those transferred, in earlier operations. Fig. 5' is a. sectional 'sideelevation Sl'IHllfil to those shown in F1gsp3' and 4,

showing the piled blanks of Figs. 4 in the next step of the transfer operation; Fig. 6 is a sectional side elevation showing the piled blanks of Figs-4 and5 at the end of their transverse movementon the hot bed and in position to be moved longitudinally from the hot bed to the shear orother place of disposal. Fig. 7 is a plan, and Fig. 8 a sec tional end elevation, on the line VIII-VIII of Fig. 7, on a larger scale showing a detail of one ofthe sliding frames and its tilting dogs and the .ways .01 supports for the frame. Fig. 9- is a sectional detail of the angle plates inv which the pins-or stops 29 are adjust-ably secured. i t

My, invention relatesto apparatusused in handling materials manufactured in a rolling mill, and it more particularly relates to such apparatus used in handling long,.thin

pipe skelp bars, plates and similar flexible j materials rolled in such nlills'while they are being cooled on the hot bed fromthe comparatively high temperatures, at'which they reach of t "Ol ration. I vention is to provide lr'aecnamsm by which the hot beds after the completion such rolled materials are transferred sidewise out of thepath of materials delivered from the-bullhead rolls of th e rolling mill.

Anothei' object of the invention is to prov de means for transferring and piling the materials on the hot bed.

A further object of the invention isto provide an improved transfer mechanism by which inaterials are transferred sidewlse out of the path of other materials being delivered from the rolling mill, are

piled, and the piled materials are transferred as a. unit sidewise into position to be removed longitudinally from'the hotbed.

' A still further object of my invention is to provldeimproved transfer mechanism by the use of which the materials may be transferred ,sidewise to eitheror both of the oppos te sides of the central runway located 111 the middle of thewidth of such hot bed.

In the drawings, 2 represents the central runway of a hot bed on which materials are delivered from the rolls of the rolling mill; and 3, 4 are hot beds located on opposite sides of the runway 52. to whi chthe materials are transferred and on which they are supported while being cooled. On the outer sidesof, the hot beds 4: are runways 5 and 6, on wlnch the materials are finally trans- ;ferred and are moved longitudinally from the hot bed.

\Vhen thinfflexible materials are to be handled by the apparatus forming my in vent-ion, roller tables arenot necessarily used in the construction of the runways, the pinch rollers? and 8 being employed in their stead.

The top surface 'of the hotbed is provided with a series of transverse recesses 9, in

which the sliding frames 10, 11 are movably mounted. The outerends of the slides 10 and 11 are connected by links 12 and 13 to the outer end of the swinging arms- 14Q'and 15 by which they areactuated. The arms 14 and 15.are secured on the rocking shafts 16 and'17, these shafts being mounted in I suitable bearings 18. .Also secured onthe IshaftsElG and .17 are spur pinions 19, the

teeth ofwhich mesh with the teeth in the racks 20 and 21, forming part of the piston which extends intothe ends of the single acting fluid pressure cylinders 22, .22,

Each of the serio of sliding frames 10 and 11 is provided with a pivoted dog 24,

3 pulled from the hotbed to central runway 2 to the hot beds 3 or 4.

Also mounted on the sliding frames 10 and 11 is a pivoted stop 25, which is arranged so as to limit the movement of the materials pushed. from the central runway 2. The stop 25 is removably secured in one of a series of pairs of slotted openings 26 provided in each of the sliding frames so as to permit of the stops 25 being adjusted to accommodate different widths of materials rolled in such mills. In addition to the dog 24 on each of the sliding frames isa second dog 27 by which the materials are pulled from their position on the hot bed to the runway 5 or 6 ofthe hot bed. The dog 27 is arranged to tilt in one direction only, tiltingv in the opposite direction being prevented by the pin or stop 27, forming part of the sliding frame. Intermediate of the dogs 24 and 27, on each of the sliding frames, is a similar dog 28, which also is arranged to tilt freely in one direction, and is prevented by a pin28 from tilting in the opposite direc- K tion, this dog being employed to transfer materials on the beds 3 and 4 from the position in which they are pushed in the first position to be the runway 5 or 6 by the dog 27.

The stops 25 on each of the sliding frames 10 or 11 are arranged to limit the movement of materials pushed from the centralrunrespond with the way 2 by the dogs 24 located on the frames on the opposite side of the runway 2. The stops 25 are pivoted so as to swing freely in either direction except when the sliding frame is moved forwardly to the end of'its forward movement. When in this position the'lower or tail ends 25 of the stops 25 will engage with the adjustable stops 29 mounted in openings 29 in the angle plates 29" secured on the support for the central runway 2, the stops 29 being removably secured in one of the series of holes 29 which hold the stops in the proper location to cor position of the stop 25 in its adjustable slots 26 on the sliding frame.

The dogs 24 are arranged to swing in opposite directions except when incertain po sitions relative to the central runway 2.

hen the sliding frames are actuated to move the dogs 24 into contact with materiratus, a rolled blank is delivered from the rolls to the central runway 2, as is shown in Fig. 2. One of the rocking shafts 16 or 17 is then actuated to move the sliding frames connected to the shaft. As the dogs 24 on these frames approach the central runway 2. the bottom portions 24 engage with the support 30, and when the dog contacts with the skelp upon the central runway, by continuing the forward movement of the sliding frames the dog contacts with and pushes this bar from the runway 2 onto the hot bed. When the sliding frames on one side of the central runway are being employed to push a bar forward, the sliding frames on the opposite side of the runway are moved forwardly into the position shown by the sliding frame on the right-hand of Fig. 3.

.In this position the tilting stop 25 by engagement of its lower end with the pin 29 is prevented from tilting and causes the movement of the blank to be stopped at a certain predetermined position. The sliding frames on the left-hand side of the drawing are then reciproeated to bring them back into the position shown in Figs. 2 and 3. Then another blank is delivered on the central runway 2 the sliding frames on the left of the central runway 2 are again advanced when the dogs 24 will again push this blank against the stop 25.

It will be noted that the surface of the hot beds 3 and 4 is slightly lower than that of the marginal edges of the central runway 2, in this way permitting the bars being pushed to be have algteady been moved against the steps 25. en a certain predetermined number of bars have been piled in this manner. generally three, the shaft 17 is moved to bring the swinglng arms 15 and the sliding frames 11 from the position shown in F 3 and 4 into that shown by Figs. 2, 5 and 6. By this movement, the pile of three bars is moved from the position shown in Fig. 4 into that shown in Fig. 5. By again advancing the. sliding frames 11 into the PO, sition shownby Figs. 3 and 4, and then retracing them into the position shown by Figs. 2, 5 and 6, the bars are moved by the outer set of pivoted dogs 27 from the position of the bars shown in Fig. 5 to that shown in Fig. 6 of the runway by which the bars are delivered longitudinally from the hot bed. The same operations are carried out in transferring bars to the left-hand side .of the central runwayl It will be noted that in removing the bars from the central runway they are pushed by the dogs on the sliding frames located on one side of the central runway to a predetermined position on the hot bed on the opposite side of the central runway, and that in the subsequent operations they are moved step by step across the width of the hot bed by the dogs on the piled on top of any bars whichsliding frames pulling'them, in this case the bars being moved by the dogs on the same side of the central runway as that on which the bars beingmoved are located.

The advantages-of my invention will be" apparent to those skilled in the art. The

of new materials being delivered by the rolling mill to the central runway of the hot bed. Thematerial's are automatically piled during their transfer across the width of the hot bed, and the piled materials are moved as a unit from the position in which they are piled to the position on the runway on which they are removed from the hotbed. The ste by step movement of the materials, together with the piling operation I very greatly increases the capacity of the hot be p as more materials can be stocked, on the hot bed than where they are not arranged in piles. I

-Modifications in the construction and arrangement of the apparatus may of course be made within the scope ofthe claims without departing from the spirit of the invention., Forinstance, a number of pivoted dogs on the sliding frames may be varied, and the mechanism for shifting the slides may be changed,- as I do not Wish to be understood as limiting myself to the precise number of dogs shown nor to the specific mechanism for shifting the slides.

1. In a transfer mechanism for hot beds and similar apparatus, a pair of slides working in substantial parallelism, means on each slide for engaging a work-piece and moving the same by the movement of the slide, and a stop on one of" the slides for engagement by a work-piece which is being moved by the other slide; substantially as described.

Y 2. In a transfer device for. hot beds and simil'artapparatus, a sliding frame movable transversely across the hot-bed having apivoted do arranged to contact with andpush materia s onsaid hot .bed, a second sliding frame having a pivoted dog adapted to contact. with and pull materialslying on the hot bed, a stop on the second frame against which materials are pushed, the first frame, and means for actuating said frames,

saidsecond-frame being arranged to move:

the materials from the, position-into which they are pushed by the dog on thefirst frame substantially as described.

3. In a transfer device for hot beds and similar apparatus, a sliding frame movable transversely across the hot bed having a pivoted dog arranged to contact with and push materials on said hot bed, a second sliding frame having a pivoted dog adapted to contact with and pull materials lying on the hot bed, means at one side of the hot bed for actuating one sliding frame, and means in the other side of the hot bed for actuating the second sliding frame, said second frame being arranged to move the materialsfrom the position into which they are pushed by the dog of the first frame; substantially .as described. g

4. The combination of a hot bed, a runway, a pair of reciprocatory slides working transversely'across the runway and the hot bed from opposite sides of the runway, means on one slide for engaging the workpiece and removing the same from the runway to the hot bed, and means. on the other I slide for engaging the workpiece and moving it into a new position on the llOtjbBd,
